HORIZONTAL LY-SLIDING WINDOW, DOOR, OR THE LIKE.

SPECIFICATION forming part of Letters IPatent No. 520,713,dated May 29,1894.

Application filed October 31, 1893. Serial No. 489,605. (No model.)

To all whom it may concern:

Be it known that I, CARL S'tiMMERMANN, architect to the board of trade,of Munster, Westphalia, in the Kingdom of Prussia and German Empire,have invented new and useful Improvements in I-Iorizontally-SlidingWindows, Doors, or the Like, of which the 7 following is aspecification, reference being had therein to the accompanying drawings.

It is well known that the methods of window closing hitherto in use arefar from being perfect and many attempts have been made to remedy theirdefects. It has been suggested to construct windows, doors and the like,to slide horizontally and to do away with the ordinaryhinges, but thedisadvantage resulting from this construction was that they Were notair-tight.

The object of the present invention is to provide a horizontally slidingand air-tight closing sash, casement or door for windows, doors,shutters and the like, which may be opened by a simple manipulation and,in the case of windows, without the slightest interference with thecurtains or with any object placed on the window sill, and which isairtight when closed.

The invention will be more fully understood by reference to theaccompanying drawings, in which Figure l is a front view of a window.Fig. 2 is a horizontal section of the same drawn on the line C D,Fig. 1. Fig. 3 is a vertical section drawn on the line A B Fig. 2. Fig.4 is a broken section drawn on the line C D, Fig. 1, on an enlargedscale, the window being closed. Fig. 5 is a similar view to thatrepresented in Fig. 4 but with the window incompletely closed. Fig. 6 isa broken section drawn on th'elineE F Fig. 1, showing a means forrendering the windowair-tight by raising it, the window being shown inthis figure as not having been yet lifted. Fig. 7 is a similar sectionalview but showing the window lifted up. Fig. 8 is a broken section drawnon the line E F, Fig. 1, showing a method of excluding the draft bylowering the window but with the window not yet lowered. Fig. 9 is asimilar section to Fig. 8 but showing the window lowered.

The horizontally sliding sashes, easements, doors or the like, aresupported in a suitable manner by means of rollers, balls or carriers,which may be arranged either at the top or at the bottom of the saidsashes, casements or doors, and allow of the same to be moved easily andwithout much friction, and it is only at the last moment that thesashes, casements or doors are rendered air-tight by either a lifting orlowering movement accompanied by either an inward or outward movement ofthe sash, casement or door. The sash, casement or door is provided witha suitable handle h by which it may be moved.

The drawings represent a window sash suspended from rollers. The windowsash r is for this purpose provided with supporting bars Z adapted toform bearings forthe pins 2 of the suspension rollers 0 which latter runon rails s so as to enable the sash to be moved easily. The said railsmay be made of angle iron or other suitable material and are provided atthe part where the rollers rest when the window is closed with either araised portion as represented in Figs. 6 and 7 or with a depressedportion as represented I in Figs. 8 and 9. The two different levels ofthe rails are of course provided with an inclined portion between themto enable the roller to pass easily from one to the other. Besides thedifference in the level of the rails, the running edge is bent eithertoward or away from the window frame, as shown in Figs. 7 and 9, at theportion coinciding with the raised or depressed portion mentionedbefore.

The edges of the sashes are provided with inclined surfaces or grooves,which form, in conjunction with similar inclined surfaces or groovesprovided on the window frame, an airtight joint.

Figs. land 5 show joints of the aforesaid description in closed and inopen position respectively. The window sash is in this case providedwith an inclined protruding edge n, which'fits a similarly formed grooveis formed in the window frame. A crossbar q fixed to the opposite edgeof the window sash is provided with an inclined groove on on one sideand with an inclined surface f on the other side, which, in conjunctionwith a wedge shaped rail Z and an inclined surface 0 rethe window.

In the arrangement represented in Figs. 6 and 7, where the window sashis rendered airtight by a lifting movement, the arrangement is asfollows: The upper edge of the window sash is provided with inclinedsurfaces j and g which are respectively brought into contact with aninclined groove 1) and an inclined surface (1 so as to form a tightjoint. The lower edge of the sash is pro- 10 vided with two extensions aand b, a being bent at an angle in such manner that when in contact withthe inclined part of the middle piece 25, an airtight joint is alsoformed betweena and b. If the tight joint is formed I 5 through thelowering of the window as represented in Figs. 8 and 9, the arrangementadopted is very similar-to the one just de scribed. The upper edge ofthe sash is provided with a groove to and an inclined sur- 2o facez'engaging respectively with the inclined edge a: and inclined surface yon the window frame, which parts, when in contact, form a tight joint,while the extensions U r; at the lower edge of the sash are simplystraight,

the intermediate piece to forming the tight joint.

In addition to forming the tight joints as before described by means ofWedging surfaces and grooves, it is desirable to force the 0 sashes inthe one or the other direction against the window frame. This may bedone on the one hand by bending the running rails of the rollers attheir raised or depressed portions either toward or away from the windowframe in order to bring the otherwise loosely suspended sash against thewindow frame. On the other hand the arrangement adopted with the wedgeshaped grooves and surfaces draws the sash in the one or the otherdirection against the window frame and thereby increases its elfect.

It is only a matter of construction to apply the invention, asillustrated by way of example in the accompanying drawings, to doors,

blinds and the like, the principle involved being to form a tight jointall round through the lifting or lowering of the sash or door accompanied by a lateral movement, which principle may be carried intopractice by the means hereinbefore described.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. In a sliding door, window or the like, the combination, with theframe and the sliding sash, of an essentially horizontal guideway onwhich the sash is adapted to travel, said guideway having portions thatdeviate both vertically and laterally from the main portion of theguideway, whereby the sash is moved both vertically and transversely tothe guideway when the door or window is nearly closed to bring the sashtightly against the frame, substantially as described.

2. An arrangement for producing tight joints in horizontally slidingsashes, doors and the like for windows, doors and the like, consistingof means whereby the sliding sash, casement or door, when nearly in itsclosed position is varied in elevation through the difference in thelevel of the guide rail or rails on which the suspending rollers run,while at the same time a horizontal deviation of the rail in conjunctionwith inclined wedge shaped surfaces at the top, bottom and sides of thesash, door and the like, causes the sash, door or the like to be forcedtightly against the frame substantially as described.

3. In a sliding door, window or the like, the combination, with theframe and the sliding sash, of an essentially horizontal guideway onwhich the sash is adapted to travel, said.

guideway having vertical deviations for moving the sash vertically,inclines at the top, bottom and sides of the sash, and projections onthe frame for engaging each of the said inclines to move the sashtransversely to the guideway, as and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
